In terms of accuracy, how do radar and lidar systems compare generally?

Lidar generally offers greater accuracy than radar due to its ability to measure the velocity of targets with a higher precision. Lidar systems utilize laser beams, which can provide more focused and detailed distance measurements. This precision allows lidar to effectively determine the speed of a moving object with minimal interference from environmental factors, such as weather or light conditions.

In contrast, while radar systems can also measure speed, they may be affected by factors such as the angle of the radar beam, the type of surface being measured, and external conditions like rain or fog, which can scatter the radar waves and impact the accuracy. Thus, lidar's technology tends to reduce uncertainties in measurement, making it a more accurate option for speed detection in many scenarios.
